Select all equations that represent a linear function.

1 answer

The equation for a linear function is y = mx + b, where m and b are constants.

The following are examples of linear equations:

1) y = 2x + 3
2) y = -0.5x + 1
3) y = 0.8x - 4
4) 2x - y = 5
5) 3y + 2 = 0.5x

So, equations 1, 2, and 3 are linear functions.
